Demi Lovato's rehab advice: 'Fake it until you make it'

This week marks a milestone for
Demi Lovato: One year ago, she left her tour with the Jonas Brothers and entered treatment for addiction, self-harm, and an eating disorder. Now that she's finished with treatment, she feels like a whole new woman.

"I feel like I'm a totally different person today, and I've grown up a lot, and I've overcome a lot, so I'm excited about where I am in my life today," she tells MTV. "I have days where I'm cranky, but I definitely want to be there for my fans and step outside and shake their hands and be there for them too, because I'm now a role model, and I want to be there for them."

She confesses that when she left the tour, she didn't go into the treatment program voluntarily. She didn't want to be there at all. The advice that helped her change her tune? "Fake it until you make it."

"The best piece of advice is to fake it till you make it," she says. "When I first went into treatment, I didn't want to be there, and I was kind of like, 'I'll just fake it until I make it.' I stayed in there, and I started believing that I was in there for the right reasons."

For now, her advice to fans that are struggling is simply to seek help. "I would say: Speak up, and don't be afraid to get help, because it could save their lives."

Demi's third album, "Unbroken," has been extremely successful, but in order to stay healthy, the star says that she's got to strike a balance between focusing on work and focusing on her own well-being.

"I work because I love doing it, so it's hard to draw that line," she admits . "It's hard to say 'I need to stop' when I love doing what I do, but it's important to find time for myself and 'me' time, so I make sure that I find that."
